The 9630 lossless data compression processor from Hifn Inc. can compress or decompress data at up to 300MBps.

Implementing the company?s Lempel-Ziv-Stac data compression algorithm, the product has a pair of 64-byte FIFOs that buffer data to and from the system bus. A 4KB SRAM is used to store the compressed data while the output is being verified. The FIFOs allow both engines to operate at full speed over the system bus.

The 9630 uses DMA handshaking signals to control the movement of data into and out of the Source and Destination FIFOs, and includes a fault-detection feature that verifies the results of the compression engine in real time. The 9630 system bus interface supports both register I/O and single-cycle burst DMA transfers. The system interface is 16-bits wide, separate I/O data buses, and operates at 150MHz.

Product manager Glenn Haley, said, "The 9630's high-rate of compression processing is essential for the upper end of the midrange tape drive market segment, as well as the emerging virtual tape drive applications where compression is used before storing on the hard disk drive."

Offered in a 144-pin TQFP package, the device is priced at $49 in 10,000-unit quantities.
